Here is my tutorial on how to get unlimited free incoming calls and free outgoing calls. A note before you do this - I havent extensively tested the outbound calling, but the method of dialing is an UNLIMITED FREE TRIAL. That means there may be certain restrictions on outbound calls (such as a time limit, etc). 1. Register for a free inbound US number on freedigits.com: Go to freedigits.com and click "sign up" towards the upper right of the page Enter your information and click register Follow any further instructions they give you - this may consist of entering a registration code sent by email, etc. Once you have your number, make a note of your number and password for the freedigits.com site. You will need this when filling out the Sip-Voip settings. 2. Set up Sip-Voip for your freedigits account: Enter Sip-Voip on your touch and go to settings. Enter these settings: Username: Enter your freedgigits 10-digit number here. EX: 5555555555 Password: Enter your freedigits password here. EX: foo Sip-server: freedigits.net Timeout: 500 Enable NAT?: No STUN Domain: Leave blank STUN Server: Leave blank Once you have filled out these settings, you can run a test call or just try to connect to the sip-server. To call your ipod, simply dial 1(555)555-5555 (replace the 5's with your freedigits number) if you're in the us, or 001(555)555-5555 if you're outside the us. If you cannot connect to the sip-server, you have entered a setting wrong. Double-check your settings. 3. Learn how to make an outbound phone call with your freedigits number (NOTE: freedigits only allows you to accept incoming calls, not dial outbound ones. Ths method will allow you to make outbound calls.) You can do this in MobileSafari - make sure before clicking dial that your ipod is connected to the sip server. Go to http://www.voipbuster.com/en/freetrialcall.php In the "Your number" box, enter your freedigits number in international format. (EX: +15555555555, yes you can enter a plus sign on the ipod's number keyboard. Click the key that shows the plus sign, and it will bring up 3 new keys. Click the plus sign.). In the "Destination" box, type in any number, also in international format. Make sure your ipod is connected to the sip server Click the dial button on the webpage. In a few seconds, your ipod should ring. Go into Sip-Voip and answer the call. When you pick up, the destination's phone will ring. When the Destination picks up, you will be connected and able to talk, FREE FOR YOU! Hopefully this helped.
